Title: Improvements in or relating to hardness determination
Inventor: SYKE GEORGE
IPC: G01N27/80
Filed: 1963-06-12
Abstract: 1,076,168. Determining hardness of metal magnetically. BRITISH IRON & STEEL RESEARCH ASSOCIATION. June 9, 1964 [June 12, 1963], No. 23393/63. Heading G1N. Metallurgical properties (e. g. hardness) of a moving strip, rod or sheet of magnetizable material are determined by measuring its retentivity. In Fig. 1 a strip 18 successively passes through a treatment section 19, past a saturating coil 20, a first fluxgate detector 21 with an output meter 24, a demagnetizer 22, and a second fluxgate detector 23 with a meter 26. The apparatus may be operated by simply energizing the coil 20 by means of a direct current sufficient to saturate the strip, de-energizing the coil and detecting the residual magnetism by means of the fluxgate 21 the output of which may also be fed to a process control unit 25. In an embodiment of the above method the saturating coil 20, the demagnetizer 22 and fluxgate 23 only are used; the strip being first saturated, and then the demagnetizer is energized by a predetermined non-saturating current of opposite sense to that of the coil 20 and the output of the fluxgate 23 is applied to the meter 26. The demagnetizer does not completely demagnetize but rather the constant current energization thereof represents a reference level or standard of mechanical hardness, while the meter 26 indicates the deviation of the strip from such level. Alternatively the demagnetizer can be energized through a current controller 27, the output of the fluxgate 23 being applied thereto to vary the energizing, current of the demagnetizer until there is zero residual magnetism in the strip. This action is that of a null seeking servo. An ammeter 28 will indicate an approximation to the coercive force, an output from the current controller 27 or the fluxgate 23 may be used to control a process. Fig. 2 (a) shows the arrangement of a resiliently mounted head carrying a magnetizing coil 33 fluxgate 34, demagnetizing coil 35 and fluxgate 36. The head is automatically retractable away from the moving strip, by means of a trip bar arrangement 73, should a welded join approach thereto, which join might otherwise damage the head.

Title: Antenna with rapid sectoral scanning
IPC: H01Q3/00
Filed: 1963-06-12
Abstract: 1,041,545. Waveguide switches. COMPAGNIE FRANCAISE THOMSON-HOUSTON. June 12, 1963 [June 12, 1962], No. 23408/63. Heading H1W. [Also in Divisions H3 and H4] An aerial for producing a scanning beam comprises a system of primary elements, e.g. horns, located near the focus of a reflector or refracting member and energized sequentially from a single source so that the phase centre of radiation progresses along the system either in discrete steps (when the radiation is switched from one primary element to the next) or continuously (when the radiation from one primary element is smoothly reduced whilst that from the next is increased). The sequential distribution from the source to the primary element is effected by a rotatable halfwave polarizing plate 18 in a circular waveguide 20 which is fed from a rectangular guide 23 and which feeds two rectangular guides 21, 22. Rotation of the plate 18 at a speed of w varies the coupling from the guide 20 to the guides 21, 22 at rates of sin<SP>2</SP> 2 wt and cos<SP>2</SP> 2 wt, so that rotation of the plate 18 through an angle of forty-five degrees will cause the energy to be switched from one output waveguide to the other.

Abstract: 1,159,801. Embossed decorative ware. C. B. THRUSH, and M. A. THRUSH. 1 Sept., 1966 [2 June, 1965], No. 23463/65. Heading B5A. Embossed, decorative ware, e.g. a simulated metal plaque, is formed in a mould having a relief pattern on at least one surface thereof, by applying a catalytically hardenable syn. thetic resin, e.g. polyester, loaded with metal powder, e.g. copper, bronze or aluminium, which is chemically inert to the resin, so that the wt. of the metal powder is at least 60% of the weight of the resin, applying a layer of fibrous reinforcement to the resin when it has at least partially hardened, allowing the resin to harden in situ and removing the hardened article from the mould. The metal powder is preferably of a size to pass through a 200-mesh BS screen. A fixing member, e.g. a hook may be inserted before setting of the resin. The ware may be made in two layers, having a layer of resin loaded with plaster of Paris or sand applied to the metal-loaded lining of the mould. At least one colouring additive may be added.

Title: Improvements in transmitter equipment for teleprinters
Inventor: COQUELET JULES
IPC: H04L27/26
Filed: 1947-08-26
Abstract: 648,012. Type-printing telegraphy. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Aug. 26,1947, No. 23508. Convention date, June 5, 1946. [Class 40 (iii)] In a printing telegraph system in which a single distinctive frequency is used for each character or sign and is generated by the action of a vibrating blade having a natural frequency corresponding to the character, each blade is normally held under stress and is released to generate the desired frequency by means of a latch member operated by a key lever corresponding to the character to be transmitted. In the arrangement shown, which may be employed for secret transmission, two blades 7, 7<SP>1</SP> are associated with each key lever 2 to provide two different allocations of frequencies to the characters. A single electromagnet 8 or 8<SP>1</SP> co-operates with the respective set 7, 7<SP>1</SP> of blades and the output at 9 or 9<SP>1</SP> is selectively controlled by a switch (not shown). The blades 7, 71 are normally held under stress, by projections 5, 6 on a spring-biassed latching-lever 3 engaged by the end of the bar 2 and released by the depression of the key 1. The transmitter is associated with the local receiver so that when the character transmitted has been printed a solenoid 14 is operated to move downwardly an arm 15 which carries a pivoted lever 16 restoring the bar and which also carries a lever 17 actuating the latch 3 to engage the end E of the bar and to place the blades 7, 7<SP>1</SP> under stress. A device to prevent the simultaneous depression of more than one key-bar 2 comprises a set of balls 10 movable in a longitudinal groove 11 below the levers, the spacing between the balls being taken up by the lower portion of a depressed key so that a second key cannot be simultaneously operated.
